NECK-YOKECENTER.

SPECIFICATION forming part of Letters Patent No. 533,889, dated February12, 1895. Application filed November 21, 1894. Serial No. 529,545, (Nomodel.)

it "appertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention has relation to a novel improvement in neck yoke centers,the object of my invention being to provide'a rfeck yoke center thatshall be adjustable to different sized neck yokes and that shall embodya locking device preventing the unlocking of the center after it hasonce been adjusted, making my improved neck yoke adjustment positivelyactuated.

In the accompanying drawings, Figure 1 shows a perspective View of aneck yoke center embodying my'invention. A Fig. 2 is a bottom viewthereof, while Fig. 3 shows a side elevation of the locking clip and barasused in my device.

In the fulfillment of the object of my invention, which is to provide anadjustable but positive locking neck yoke center, I construct a center,A, of any suitable design, size and material, though preferably ofleather, which comprises the elongated blank, A, provided with thetongue opening, 2, and the extending portion, 3, which is re-curved toform the neck-yoke supporting loop, and terminates in a terminal loop,4, which loop is adapted to encompass and movably hold a clamping bar,c, a side elevation of which bar is shown in Fig. 3. This bar comprises,essentially, a rounded central portion ending in two terminal eyes,which eyes are adapted to work over and contain the threaded stems, a,a, of the clip, B, as is more clearly shown in Fig. 1. This bar, c,'issewed or otherwise secured within the end, 3, of the center, while theapproximately U-shaped clip, B, is adapted to stride and work over theneck portion of the center, as is shown in Fig. 3. This clip, B, may bemade 'of any suitable size, shape or material, but is preferably made ofmetal, and is provided with one or more inwardly extending pointed nibs,6, 5, as shown in Fig. 3.

This clip, B, can be made of rounded iron, having its two terminationsthreaded, while the center is preferably flattened so that it willpresent a flat riding surface, the nibs, 5, forming an integral partthereof and being upset during the same operation that the bar iscentrally flattened. The stems, a, a, of the clip are provided withsuitable niits, e.

In assembling my improved neck yoke center, the bar, 0, having beenpreviously secured within the upper end thereof, the clip is made toencompass the center from above, striding the neckrportion, while thethreaded stems, a, a, are passed through the eye openings of the bar, 0.The nuts, e, e, are then fixed-and adjusted until they thread themselvesdown upon the bar. It should be stated here that the bar, 0, is adjustedin length so that when the nuts, 6, e, are adjusted they fit snuglyagainst the sides of the terminal loop of the center, so that as thesenuts are tightened they have to successively press the leather asideuntil A they find a seating upon the eyes of the bar, 0, as will benoticed in referring to Fig. 3, where the re-curve'd neck portion, 4, isshown as looking the nuts, 6, to the threaded stems, a, a. 7

It is of course understood by those familiar with the art, that theseneck yoke centers are being continually agitated, so that anything thatis secured by nuts would be likely to, in the course of'time, unlock.This isa very important feature of my invention, as it absolutelyprevents the unlocking of these adjusting nuts and so makes the devicepositively actuated.

As illustrated, I have shown the bar, 0, as passing th rough'theterminal loop of the center, but it is of course understood that theclip, B, could be made to pass through this terminating loop, 4, and beclamped upon the outside to the bar, 0, and the bar, 0, be provided withthe impinging nibs, 5, thereby reversing the clip. So, also, could thebar, B,

and the stems, a, be separate, the bar, B, and bar, 0, being clampedtogetherby bolts pass ing through the eyesin the bar, 0, and threadingin the ends of the bar, B, being adjustably secured thereto. Thisbinding clip can, of course, be unlocked in forcing the nuts in theopposite direction which of course gradu ally forces the leather out,which, to a great degree is pliable, so that the adjustment can beimparted to the center. So, also, it will be noticed that the bar, a,being round, adjusts itself within the terminal loop of the center, sothat the flat side of the eye of the bar, 0, the nuts, 6, e, and thebinding surface of the clip, B, are always in the same plane and sosnugly register.

Now, having thus described my said invention, what I claim as new, anddesire to secure by United States Letters Patent, is-

In an adjustable neck yoke center, the combination, with a bar revolublyheld within the terminal loop of said neck yoke center, said bar beingprovided with two terminal eyes, of a striding binding clip riding oversaid neck yoke center and being adapted to engage said revolubly heldbar, the terminal stems of said clip being threaded and at an angle tothe body of said clip, and being adapted to extend through said terminaleyes, said clip being provided with one or more impinging nibs adaptedto embed within said center, and nuts adapted to thread upon saidterminal stems and look upon said revolubly held bar and against saidterminal loop, to positively lock said nuts, all substantially as andfor the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
